Purity you can prove.
Science you can cite.
Pharmaceutical-grade research peptides, each lot mass-verified by independent HPLC and shipped with its own certificate of analysis.
Lot-verified research peptides
Every vial ships with its own certificate.
We don't ask you to trust a batch average. Each lot is independently tested and given a unique certificate of analysis you can match to the lot number printed on your vial.
VERIFIED
From sequence to sealed vial
Solid-phase synthesis
Sequences are assembled by Fmoc solid-phase peptide synthesis, then cleaved and precipitated under controlled conditions.
Preparative HPLC
Crude peptide is purified by preparative reverse-phase HPLC and the target fraction is collected to ≥99% homogeneity.
Independent assay
Identity and purity are confirmed by analytical HPLC and mass spectrometry at third-party laboratories before release.
Built to a standard,
not a shortcut.
BioPura operates from an ISO-certified facility with documented quality systems and a chain of custody from synthesis to shipment.

Questions,
answered plainly.
All BioPura products are sold strictly for in-vitro laboratory research and development. They are not drugs, supplements, or medical devices, and are not intended for human or veterinary use, consumption, or clinical application.
Each vial's lot number matches a unique COA. The certificate lists the assay purity (by RP-HPLC), confirmed molecular identity (by mass spectrometry), net peptide content, and the testing laboratory. Match the lot on your label to the COA on the product page.
Lots are independently verified by accredited analytical laboratories. Results are published unedited on each product page, including the chromatogram and method parameters.
Lyophilized peptides are shipped in insulated, ice-packed packaging and dispatched within 24 hours. We recommend storing unreconstituted peptides at -20°C and reconstituted material at 2–8°C.
We release lots at ≥99% assay purity. The measured value is printed on the label and certificate; if a lot does not meet specification, it is not released for sale.
